Dhondy Posted December 10, 2008 Posted December 10, 2008 Not to mention providing antioxidants. Why don't vitamins C & E prevent cancer?
Brainfade Posted December 10, 2008 Posted December 10, 2008 Why don't vitamins C & E prevent cancer? Am not sure I understand the question. What I am saying is that fruits and vegetables provide fiber (which mentioned), and they provide antioxidants. Are you saying that Vitamin C and Vitamin E don't prevent cancer? Or are you saying that I am saying that they don't prevent cancer? In lab situations, Vitamin C has been shown to be effective as an anti-cancer agent. Am not so sure about Vitamin E. And I am not so sure about Vitamin C in a clinical setting, although a quick Google shows me that recent studies have cast doubt on the anticancer properties of Vit C and E supplements http://www.nlm.nih.gov/medlineplus/news/fullstory_71702.html Back to "An apple a day ..." With regard to regularly exercise, eating healthy, and not smoking and drinking - none of that helped my father. He did all of that, but succumbed to AML (the most insidious of leukemias, as I understand it :(.
Dhondy Posted December 10, 2008 Posted December 10, 2008 Sorry about your dad. A, C & E are really good anti-oxidants, as is selenium, but none of them have been shown to prevent cancer in RCTs, which were specifically designed to prove/disprove their role, after encouraging reports from observational studies. (you remember that myth about HRT preventing heart disease, generated in the same way?) Do external anti-oxidants, scavenging free radicals, prolong life by preventing cancer? Maybe on the bench, but not at bedside yet.

What do you think about all this new research coming out with statin-inflammation-heart disease connection, and the recommendation that one take statin as part of a "lifestyle adjustment" if one is at risk for heart disease?
Dhondy Posted December 10, 2008 Posted December 10, 2008 What do you think about all this new research coming out with statin-inflammation-heart disease connection' date=' and the recommendation that one take statin as part of a "lifestyle adjustment" if one is at risk for heart disease?[/quote'] There was a pretty pertinent study on it recently, I think in the NEJM, which showed that rosuvastatin was effective in primary prevention of CHD and related stuff, but only in those with increased levels of high sensitivity CRP. And these guys had pretty low cholesterol, something like a mean of 3.5 mmol/l.

Mr. Wicket Posted December 11, 2008 Posted December 11, 2008 Because any 'distilled water' has some gas in it (CO2 usually) that dissolves. CO2 in water forms H2CO3, which is a weak acid.
